Suggest you post up the details of the system.
IE:
Pump is stock, Walbro, etc?
Returnless plumbed?
Adj regulator? if so, is it boost referenced?
Stock pump location?
Electrical system to pump is?
Base psi, and the psi @ 5000?
Data logs available?
How is the engine tuned?

Returnless Plump? Yes
Adj Regulator? No (60psi) Is it Boost referenced? No
Stock Pump Location? In-Tank
Electrical System to pump is? Stock (Bolt-on)
Base psi? 11psi psi @ 5000? 11psi
Data Logs available? No, because i tried cruising in it and accelrating the fuel pressure drops down instead of keeping stable or going above.
How is engine tuned? Engine tuned on Dyno and is perfectly tuned upto 4500rpm because after that the fuel pressure drops and down and the engine doesn't get enough fuel.
The main problem that i am facing is that when i cruise in my truck the fuel pressure is not constant, it keeps dropping, i have checked all the electrical wirings and lines and everything seems to be well fitted. But when i accelerate the fuel pressure drops down and the car starts to jump like it doesn't have fuel, (like it loses rpm and goes up again)...
I am trying to tune it but i can't go above 5000rpm where the fuel pressure falls down straight away...
Will the fuel catch tank solve the problem, and how does it work if it will?
Thanks
I really appreciate any help, Thanks again to everyone in advance..
